An airplane pilot fell to the ground after jumping from an aircraft without his parachute opening. He lands in a snowbank, creating a crater 2.1 m deep, but survived with only minor injuries.  Assuming the pilot’s mass was 68 kg and his terminal velocity was 35 m/s (the velocity at the point he stopped accelerating on his way down), what is: a) the average force exerted on him by the snow in bringing him to rest?  b) the work done by the snow?
